Description
Technical field
The utility model relates to a kind of small stair dimension measurement tool.
Background technology
The principle of work of clock gauge is: the small rectilinear movement of the sounding rod caused by measured size, amplifies through gear drive, becomes and refers to the rotation of meter on index dial, thus read the size of measured size.Generally in surveying work, sounding rod is reached position to be measured by the gauge outfit of the hand-held clock gauge of user, and the indicators turn of observation gauge outfit reads reading.But there is the step that some are small in a lot of workpiece, this kind of step is often arranged in a groove, the sounding rod of clock gauge can not stretch into, and also just can not measure the size of small stair, therefore needs to develop a kind of special small stair dimension measurement tool.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of small stair dimension measurement tool, and pass to clock gauge thus the size measuring small stair by measuring leg by measuring displacement, structure is simple, easy to use.
The utility model solves the technical scheme that its technical matters adopts:
A kind of small stair dimension measurement tool, include body and clock gauge, described body is provided with storage tank, the sounding rod of described clock gauge is arranged in described storage tank, described body is provided with mounting groove away from the one end on clock gauge surface, bearing pin is provided with in described mounting groove, described bearing pin is hinged with swinging block, described swinging block is L-type, it is outer and be provided with the measurement leg of inclination that mounting groove is stretched out in the outer end of swinging block, the inner of swinging block is stretched in storage tank, described the inner is provided with groove, steel ball is provided with in described groove, described steel ball is connected to the contact of sounding rod by extension rod, described the inner is connected with caging bolt, and described caging bolt is fixed on body, caging bolt is set with the back-moving spring between the inner and body.
As the improvement of technique scheme, the surface of described clock gauge is provided with two locating pieces for location survey bound.
As the further improvement of technique scheme, the angle between described measurement leg and outer end is 45 °, and the end of described measurement leg is provided with rounding.
Further, described body is provided with the locking device for locking dial gauge sounding rod.
Further, described locking device comprises two symmetrically arranged latch segments, and leave gap between described two latch segments, two latch segment ends are provided with clamping screw.
The beneficial effects of the utility model are: measure leg and be displaced through the sounding rod that swinging block is delivered to clock gauge in measuring process, thus demonstrate reading on clock gauge; Be obliquely installed owing to measuring leg, be convenient to the micro-locality stretching into workpiece; Swinging block is that the shift length at its swing type two ends of L-type linearly changes, and utilizes the angle change of the inner of the spherical elimination swinging block of steel ball in swing process; Caging bolt and back-moving spring restriction swinging block make steel ball be in the reference position of the contact by extension rod contact measurement bar, and after measurement terminates, back-moving spring promotes swinging block and gets back to reference position.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is front view of the present utility model;
Fig. 2 is left view of the present utility model.
Embodiment
With reference to Fig. 1 ~ Fig. 2, a kind of small stair dimension measurement tool, include body 1 and clock gauge 2, described body 1 is provided with storage tank 101, the sounding rod 201 of described clock gauge 2 is arranged in described storage tank 101, described body 1 is provided with mounting groove 102 away from the one end on clock gauge 2 surface, bearing pin 103 is provided with in described mounting groove 102, described bearing pin 103 is hinged with swinging block 3, described swinging block 3 is in L-type, it is outer and be provided with the measurement leg 303 of inclination that mounting groove 102 is stretched out in the outer end 301 of swinging block 3, the inner 302 of swinging block 3 is stretched in storage tank 101, groove is provided with on described inner 302, steel ball 4 is provided with in described groove, described steel ball 4 is connected to the contact of sounding rod 201 by extension rod 7, be connected with caging bolt 5 on described inner 302, described caging bolt 5 is fixed on body 1, caging bolt 5 is set with the back-moving spring 6 between inner 302 and body 1.In the present embodiment, during measurement, measurement leg 303 is reached measuring position contact workpiece by the hand-held clock gauge 2 of user, measure leg 303 after the small stair of contact workpiece produces displacement, swinging block 3 rotates around bearing pin 103, the inner 302 of swinging block 3 promotes sounding rod 201 is passed in displacement by steel ball 4 contact by extension rod 7, then demonstrates reading on the surface of clock gauge 2.It is wider that measurement leg 303 is obliquely installed usable range, caging bolt 5 and back-moving spring 6 limit swinging block 3 make it remain on reference position (namely steel ball 4 abuts extension rod 7 lower end, extension rod 7 upper end abuts the contact of sounding rod 201), and back-moving spring 6 gets back to reference position at measurement acceptance promotion swinging block 3.
In the present embodiment, preferably, the surface of described clock gauge 2 is provided with two locating pieces 202 for location survey bound.By the bound of locating piece 202 calibration measurements on the surface of clock gauge 2, whether user observes indicator and swings and exceed locating piece 202 and can determine measurement data whether within acceptability limit when measuring, accelerate measuring speed, raise the efficiency further.
In the present embodiment, preferably, the angle between described measurement leg 303 and outer end 301 is 45 °, and the end of described measurement leg 303 is provided with rounding, and rounding is conducive to measuring leg 303 contact surface.
